TECHNIQUE OF EYE DISSECTIONS 



on, will show these two chambers in section. 

 One will gain a much clearer conception of 

 their construction in that section than in the 

 "anterior half " specimen. 



Now, remove the lens, using the point of 

 the scalpel to cut through the suspensory liga- 

 ment close to the lens. When this has been 

 done there will be seen in the anterior cham- 

 ber a thin, watery liquid the aqueous humor. 



The corona ciliaris and orbicularis ciliaris 

 may be better seen and studied if viewed 

 through a hand lens. 



THE IRIS 



To see the iris, take hold of the cut edge of 

 the dhoroid, and, gently pulling, separate it 

 from its attachment to the corneo-scleral junc- 

 tion. The white ring on the anterior surface 

 of this part of the second coat of the eye is 

 the ciliary ring. With a scissors, cut around 

 this ciliary ring at its outer edge. This speci- 

 men will show the anterior surface of the iris, 

 and on the posterior side it will show the close 

 relationship between the iris and the ciliary
